Hey guys, Good info here. I have been doing 12 - 16 day trips in BC and Alaska with a Sevlor inflatable kayak. Weight is important as we either fly in or fly out. It's time to get a bigger boat and I'm not sure wether to go with a raft or cata raft. Thinking about the Aire puma. What are the advantages or disadvantages of a raft over a cataraft?
